When teaching solid shapes, let children eat the shapes. For spheres eat Reese Bites. For rectangle prisms, eat sugar wafers. For cubes, eat cubes of cheese. For cylinders, eat marshmallows. For cones, eat Bugle's.

Use toothpicks and marshmallows to create "see-through" solid shapes. Students will be able to view how putting shapes together form new shapes.

Use paint and paper to teach symmetry. Paint only 1/2 of the paper, fold, press and open. You will see a symmetrical picture.

Hula hoops are not only great items to use to create venn diagrams, but use them to make "kid clocks". One student holds the hula hoop up the other uses his/her arms to set the time for other to guess. Outdoors they can lay in the grass.
